[0033] The present disclosure provides a control system. In some embodiments, the control system includes a processing device (such as the processing device 110 described below Figure 1 shown) and a rotating device (such as the rotating device 123 described below Figure 1 shown). The processing device is configured to receive an input signal and generate a control signal based on the input signal. The rotating device has a first angular momentum, and when the input signal changes, the first angular momentum changes in response to the control signal.
[0034] In some embodiments, the processing device is further configured to identify at least one of image data and sound data of the input signal, and generate a control signal based on at least one of the image data and the sound data. When at least one of the image data and the sound data changes from a first data value to a second data value, the first angular momentum changes in response to the control signal.
[0035] Figure 1 FIG. 12 is a schematic diagram of a control system 100 according to some embodiments of the present disclosure. The control system 100 includes a processing device 110, a handheld device 120, an audio-visual device 130, and a host 140. The processing device 110 receives an input signal IS1 and generates a control signal CS1 based on the input signal IS1. The handheld device 120 operates according to the control signal CS1. The host 140 generates the input signal IS1. The audio-visual device 130 generates images and / or sounds based on the input signal IS1.
[0036] In some embodiments, the host 140 can be implemented by a game console, and the audio-visual device 130 can be implemented by a screen and / or a speaker, but the present disclosure is not limited thereto. In some embodiments, the input signal IS1 includes image data and sound data, the audio-visual device 130 displays corresponding images based on the image data and generates corresponding sounds based on the sound data, and the processing device 110 generates a control signal CS1 based on at least one of the image data and the sound data. It should be noted that the input signal IS1 received by the audio-visual device 130 and the processing device 110 is the same. In some embodiments, the host 140 can provide the input signal IS1 to each of the audio-visual device 130 and the processing device 110 through a splitter.
[0037] As shown in Figure 1As shown, the handheld device 120 can include a handheld component 121, a driving device 122, and a rotating device 123. The handheld component 121 can be grasped by a user. The rotating device 123 is disposed on the handheld component 121 and can rotate to have an angular momentum L1. In some embodiments, the rotating device 123 can be a turntable, a sphere, a gyroscope, or other structures that can generate angular momentum by rotation. The driving device 122 can adjust the rotating device 123 according to a control signal CS1 to change the angular momentum L1. In other words, the angular momentum L1 changes in response to the control signal CS1.
[0038] In some embodiments, the processing device 110 can identify at least one of the video data and the audio data of the input signal IS1 to determine the angular momentum L1, such that the angular momentum L1 corresponds to at least one of the video and the audio of the audio-visual device 130. In some embodiments, the processing device 110 can identify the video data and the audio data of the input signal IS1 through artificial intelligence, such as an object detection model of YoloV3, but the present disclosure is not limited thereto. In various embodiments, the processing device 110 can identify through various models.
[0039] In Figure 1 In the illustrated embodiment, the rotation axis of the rotating device 123 is parallel to the Z axis entering the paper surface. In other words, the rotating device 123 rotates in the X-Y plane. In some embodiments, the X axis, the Y axis, and the Z axis are perpendicular to each other. When the user rotates the handheld device 120 in the Z direction such that the rotation direction of the rotating device 123 changes, due to the law of conservation of angular momentum, the user will feel a resistance force from the handheld device 120. The greater the angular momentum L1, the greater the resistance force. Therefore, the control system 100 can change the resistance force felt by the user by changing the angular momentum L1.
[0040] In some methods, the processor controls the motor according to a signal generated by a host (such as a game console) to vibrate a device (such as a game controller, a wearable device, a head-mounted device, a controller, etc.) or adjust the key resistance. However, in the above methods, the device does not generate a corresponding resistance force when rotated by the user. Therefore, the user cannot feel the sense of weight.
[0041] Compared with the above methods, in the embodiments of the present invention, the processing device 110 determines the angular momentum L1 according to different video data and / or audio data, such that the user can feel corresponding different resistance forces through the handheld device 120. In this way, when the user operates the handheld device 120 or other devices (such as a game controller, a wearable device, a head-mounted device, a controller, etc.), the user can feel the sense of weight of objects and / or situations corresponding to different videos and / or different sounds, thereby improving the feel or the experience.
[0042] InFigure 1 In the illustrated embodiment, the handheld component 121 has a length X1 in the X direction, a length Y1 in the Y direction, and a length Z1 in the Z direction, where the length X1 is greater than each of the length Y1 and the length Z1. In some embodiments, the user most often rotates the longest side of the handheld component 121, that is, the side having the length X1. Correspondingly, the rotation axis direction of the rotating device 123 is perpendicular to the X direction, so that the user can feel the resistance when rotating the handheld component 121.
[0043] In some embodiments, the angular momentum L1 can be represented by the following formula 1, where the mass M1 represents the mass of the rotating device 123, the distance R1 represents the distance between the mass of the rotating device 123 and the rotation axis of the rotating device 123 (for example, the mass of the rotating device 123 can come from the weight blocks B11 and B12, and the distance R1 can represent the distance between the weight blocks B11 and B12 and the rotation axis of the rotating device 123), and the angular velocity W1 represents the angular velocity of the rotating device 123, that is, the rotational speed.
[0044] L1 = M1 × R1 2 × W1 (Formula 1).
[0045] As can be seen from Formula 1, the driving device 122 can change the angular momentum L1 by changing at least one of the distance R1 and the angular velocity W1. For example, the driving device 122 can increase the angular velocity W1 to increase the angular momentum L1. For another example, the driving device 122 can also decrease the distance R1 to decrease the angular momentum L1.
[0046] As Figure 1 shown, the rotating device 123 can include weight blocks B11 and B12, and the distance R1 can represent the distance between the weight blocks B11 and B12 and the rotation axis of the rotating device 123 in the X-Y plane. In some embodiments, the driving device 122 can change the distance R1 by adjusting the positions of the weight blocks B11 and B12.
[0047] In some embodiments, the processing device 110 can store data on the relationship between the angular velocity W1, the distance R1, and the image data and sound data of the input signal IS1. In Figure 1 the illustrated embodiment, the processing device 110 stores the relationship between the angular velocity W1, the distance R1, and the input signal IS1 as a look-up table T1, but the present disclosure is not limited thereto. In various embodiments, the processing device 110 can store the relationship between the angular velocity W1, the distance R1, and the input signal IS1 in various forms.
[0048] As shown in the lookup table T1, the video data of the input signal IS1 can have data values corresponding to three different weapons: a small knife, a small gun, and a large gun. Among the settings of the input signal IS1, the weight of the large gun is greater than that of the small gun, and the weight of the small gun is greater than that of the small knife. Correspondingly, the values of the rotational speed W1 corresponding to the large gun image, the small gun image, and the small knife image are 2000, 500, and 0 respectively. In this way, the resistance felt by the user when the large gun image is displayed on the audio-visual device 130 is greater than the resistance felt when the small gun image is displayed on the audio-visual device 130, and the resistance felt by the user when the small gun image is displayed on the audio-visual device 130 is greater than the resistance felt when the small knife image is displayed on the audio-visual device 130. In some embodiments, the rotational speed corresponding to the small knife image is 0, so that the corresponding resistance is 0.
[0049] In some embodiments, when the user operates to change the video data of the input signal IS1, the rotational speed W1 also changes accordingly. For example, when the user switches from the small gun to the large gun, causing the audio-visual device 130 to change from displaying the small gun image to displaying the large gun image, the rotational speed W1 changes from 500 to 2000, and the angular momentum L1 increases correspondingly. Take another example, when the user switches from the small gun to the small knife, causing the audio-visual device 130 to change from displaying the small gun image to displaying the small knife image, the rotational speed W1 changes from 500 to 0, and the angular momentum L1 decreases correspondingly.
[0050] On the other hand, the audio data of the input signal IS1 can have data values corresponding to two different states: the normal state or the tired state of the game character. Among the settings of the input signal IS1, the sense of weight in the tired state is greater than that in the normal state. Correspondingly, the values of the distance R1 corresponding to the normal state and the tired state are 30 and 80 respectively. In this way, the resistance felt by the user when the audio-visual device 130 produces the sound of the tired state is greater than the resistance felt when the audio-visual device 130 produces the sound of the normal state.
[0051] In some embodiments, the processing device 110 can also judge the state of the game character through the video data of the input signal IS1. For example, judge whether the game character is in the normal state or the tired state through the blood volume video data in the video data. In other words, the above operation of adjusting the angular momentum L1 according to the normal state and the tired state can also be performed according to the video data of the input signal IS1.
[0052] In some embodiments, when the user operates to change the audio data of the input signal IS1, the distance R1 also changes accordingly. For example, when the user switches from the normal state to the fatigued state, causing the audio-visual device 130 to change from generating normal-state sounds to generating fatigued-state sounds, the driving device 122 will drive the weights B11 and B12 to change the distance R1 from 30 to 80 from the axis of rotation, and the angular momentum L1 correspondingly increases. To give another example, when the user switches from the fatigued state to the normal state, causing the audio-visual device 130 to change from generating fatigued-state sounds to generating normal-state sounds, the driving device 122 will drive the weights B11 and B12 to change the distance R1 from 80 to 30 from the axis of rotation, and the angular momentum L1 correspondingly decreases.
[0053] Please refer to the look-up table T1 and formula 1. When the input signal IS1 corresponds to a small knife, since the angular velocity is 0, the value of the angular momentum L1 is 0. When the input signal IS1 corresponds to a small gun and the normal state, the value of the angular momentum L1 is M1×30 2 ×500. When the input signal IS1 corresponds to a small gun and the fatigued state, the value of the angular momentum L1 is M1×80 2 ×500. When the input signal IS1 corresponds to a large gun and the normal state, the value of the angular momentum L1 is M1×30 2 ×2000. When the input signal IS1 corresponds to a large gun and the fatigued state, the value of the angular momentum L1 is M1×80 2 ×2000.
[0054] In summary, in response to two different video data values (small gun and large gun) and two different audio data values (normal state and fatigued state), the angular momentum L1 can have four different angular momentum values. The video data values, audio data values, distance R1 values, and rotational speed W1 values shown in the look-up table T1 are only examples, and the present disclosure is not limited thereto. In various embodiments, the processing device 110 can adjust the distance R1 and the rotational speed W1 in various ways according to various video data values and audio data values. For example, the processing device 110 can also change the distance R1 when the video data changes, and can also change the rotational speed W1 when the audio data changes.
[0055] Although in the above embodiments, the video data corresponds to a weapon and the audio data corresponds to a state, the present disclosure is not limited thereto. In various embodiments, the video data can also correspond to an object or other information other than a weapon, and the audio data can also correspond to an object or other information other than a state. For example, in some variations, the video data corresponds to a state and the audio data corresponds to a weapon.
[0056] Figure 2 Schematic diagram of a handheld device 200 according to some embodiments of the present case. Please refer to Figure 1and Figure 2 The handheld device 200 is a variant of the handheld device 120. Some components of the handheld device 200 follow the same numbering method as those of the handheld device 120. For the sake of simplicity, the discussion will focus on the differences between the handheld device 200 and the handheld device 120 rather than the similarities.
[0057] Compared with the handheld device 120, the handheld device 200 further includes driving devices 212, 222 and rotating devices 213, 223. The rotating device 213 is disposed on the handheld part 121 and can rotate to have an angular momentum L2. The driving device 212 can adjust the rotating device 213 according to the control signal CS1 to change the angular momentum L2. The rotating device 223 is disposed on the handheld part 121 and can rotate to have an angular momentum L3. The driving device 222 can adjust the rotating device 223 according to the control signal CS1 to change the angular momentum L3. In other words, the angular momenta L2 and L3 change in response to the control signal CS1.
[0058] In Figure 2 the illustrated embodiment, the rotating devices 213, 223 and 123 are separated from each other along the X axis. However, the present disclosure is not limited thereto. Various positional relationships of the rotating devices 213, 223 and 123 are contemplated within the scope of the present disclosure. For example, the rotating devices 213, 223 and 123 can also be integrated in the same device, coupled to each other, and located at the same position.
[0059] As Figure 2 illustrated, the rotation axis of the rotating device 213 is parallel to the X axis. In other words, the rotating device 213 rotates in the Z-Y plane. When the user rotates the handheld device 200 in the X direction so that the rotation direction of the rotating device 213 changes, due to the law of conservation of angular momentum, the user will feel a resistance force from the handheld device 200.
[0060] Similarly, the rotation axis of the rotating device 223 is parallel to the Y axis. In other words, the rotating device 213 rotates in the Z-X plane. When the user rotates the handheld device 200 in the Y direction so that the rotation direction of the rotating device 223 changes, due to the law of conservation of angular momentum, the user will feel a resistance force from the handheld device 200.
[0061] In this way, when the user rotates the handheld device 200 in different directions, at least one of the rotating devices 123, 213 and 223 will generate a corresponding resistance force, so that the user can feel the somatosensation of the image and / or sound of the corresponding audio-visual device 130.
[0062] In some embodiments, the values of the angular momenta L1 to L3 are the same as each other, such that when the user rotates the handheld device 200 in different directions, the user can feel the same magnitude of resistance. For example, when the image and sound of the audio-visual device 130 change from the small gun / normal state to the large gun / tired state, the value of each of the angular momenta L1 to L3 changes from M1×30 2 ×500 to M1×80 2 ×2000.
[0063] In some embodiments, each of the rotating devices 213 and 223 includes weight blocks (not shown in the figure) similar to the weight blocks B11 and B12, and / or the driving devices 212 and 222 can adjust the distance between the weight blocks in the rotating devices 213 and 223 and the corresponding rotation axes to change the angular momenta L2 and L3.
[0064] In some embodiments, when the image data has a first image data value and the sound data has a first sound data value, the first driving device adjusts the first angular momentum to a first angular momentum value. For example, when the image data has an image data value corresponding to a small gun and the sound data has a sound data value corresponding to the normal state, the driving device 122 adjusts the angular momentum of the rotating device 123 to an angular momentum value of 500*30.
[0065] In some embodiments, when the image data has a second image data value and the sound data has a first sound data value, the first driving device adjusts the first angular momentum to a second angular momentum value. For example, when the image data has an image data value corresponding to a large gun and the sound data has a sound data value corresponding to the normal state, the driving device 122 adjusts the angular momentum of the rotating device 123 to an angular momentum value of 2000*30.
[0066] In some embodiments, when the image data has a first image data value and the sound data has a second sound data value, the first driving device adjusts the first angular momentum to a third angular momentum value. For example, when the image data has an image data value corresponding to a small gun and the sound data has a sound data value corresponding to the tired state, the driving device 122 adjusts the angular momentum of the rotating device 123 to an angular momentum value of 500*80.
[0067] In some embodiments, when the image data has a second image data value and the sound data has a second sound data value, the first driving device adjusts the first angular momentum to a fourth angular momentum value. For example, when the image data has an image data value corresponding to a large gun and the sound data has a sound data value corresponding to the tired state, the driving device 122 adjusts the angular momentum of the rotating device 123 to an angular momentum value of 2000*80.
[0068] In some embodiments, the first image data value is different from the second image data value. For example, the image data value corresponding to the small gun is different from the image data value corresponding to the large gun.
[0069] In some embodiments, the first sound data value is different from the second sound data value. For example, the sound data value corresponding to the normal state is different from the sound data value corresponding to the fatigued state.
[0070] In some embodiments, the first angular momentum value, the second angular momentum value, the third angular momentum value, and the fourth angular momentum value are different from each other. For example, the angular momentum values of 500*30, 2000*30, 500*80, and 2000*80 are different from each other.
[0071] In some embodiments, the handheld component has a first length in a first direction, a second length in a second direction, and a third length in a third direction, the first length being greater than each of the second length and the third length, and the axis direction of the first rotating device being perpendicular to the first direction. For example, the handheld component 121 has a length X1 in the X direction, a length Y1 in the Y direction, and a length Z1 in the Z direction, where the length X1 is greater than each of the length Y1 and the length Z1, and the axis direction of the rotating device 123 is perpendicular to the X direction.
[0072] Although the present disclosure has been disclosed above by way of embodiments, it is not intended to limit the present disclosure. Any person having ordinary knowledge in the technical field to which the present disclosure pertains may make some modifications and refinements without departing from the spirit and scope of the present disclosure.
